Weather updated Friday, January 1 2021
As the driest calendar year in Flagstaff’s recorded history it can only get better.
On December 28 and 29, the season's second most productive snow storm gave us 7” of cold, low density powder at 10,800 feet. Strong post-frontal northeasterly winds redistributed much of this, and no doubt sent some of it skyward back into the atmosphere. Cold temperatures and a few flurries rounded out the week as another dry low pressure system passed close by.
Conditions will settle for the weekend. We will return to a pattern of episodic low moisture troughs passing by, but with limited impact. These will bring cool temperatures and turbulent weather, but little hope for significant recovery from our lean snowpack. The most promising of these disturbances appears to be about a week out.
Snowslide SNOTEL reports 12” of snow at 9,730’ on Thursday, December 31. Since Friday, December 25 Snowslide SNOTEL low temperatures have ranged between 3°F on December 30 and 27°F on December 27, while highs have ranged from 25°F on December 29 to 47°F on the 26. ASBTP station is currently not operational. Between the same period, the new Grand Canyon Express weather station (AU373) at 10,767' reported a maximum temperature of 34°F on December 26, with a minimum of 6°F on December 29. So far this winter we have had a total of 34” of snowfall at 10,800 feet.
